 feeders. They attack a great va- 

 riety of substances ranging from 

 the most succulent foliage to dried 

 grains and wood of trees. Many 

 are of great importance to farm- 

 ing and to other industries. The 

 adults are rarely of direct impor-

 are commonly grouped together 

 under this heading on account of 

 their general similarity and small 

 size. In contra-distinction to these 

 all other Lepidoptera are called 

 the "Macro-Lepidoptera." 



The families or super-families 

 comprising this group all contain 

 species of considerable importance. 

 Some of these may be used to 

 illustrate the families. The first 

 of the groups is the Pyralidina. 

 The moths in this group are often 

 fairly large for "Micros." Their 

 wings are usually rather regular 

 in outline and often folded or 

 rolled about the body when at
